NCP1800_04 Datasheet, PDF (1/14 Pages) ON Semiconductor – Single-Cell Lithium Ion Battery Charge Controller

NCP1800
Single−Cell Lithium Ion
Battery Charge Controller
The NCP1800 is a constant current, constant voltage (CCCV)
lithium ion battery charge controller. The external sense resistor sets
the full charging current, and the termination current is 10% of the
Full−Charge current (0.1 C). The voltage is regulated at ±1% during
the final charge stage. There is virtually zero drain on the battery when
the input power is removed.
